简要总结
Primary Objective:
To evaluate the efficacy of sarilumab at Week 16 in participants with non-infectious uveitis (NIU).
Secondary Objectives:
To evaluate the change in best corrected visual acuity (BCVA). To evaluate the safety of subcutaneous sarilumab in participants with NIU. To evaluate the change in macular edema. To evaluate the change in other signs of ocular inflammation. To evaluate the effect on retinal vessel leakage. To evaluate the effect of sarilumab on reducing concomitant immunosuppressant therapy.
To evaluate the change in ocular inflammation in the anterior chamber. To evaluate the pharmacokinetics of sarilumab in NIU participants. To evaluate the immunogenicity with anti-drug antibodies (ADA).
详细描述
The total duration per participant was up to 58 weeks, which included a 2 week screening period, 16 weeks principal treatment period (Part A), 34 weeks extension treatment period (Part B) or open label treatment period (Part C), and 6 weeks after last treatment administration.
Participants with decrease in vitreous haze (VH) ≥2; or corticosteroids dose <10 mg/day at Week 16 were considered as responders. Participants who did not complete the principal treatment period (Part A) due to lack of efficacy; or no decrease in VH ≥2 and corticosteroids dose ≥10 mg/day at Week 16; or no decrease in VH ≥2 and corticosteroids dose missing at Week 16; or non-responder according to medical review, were considered as non-responders.
Responder participants, observed at Week 16 (at the end of Part A), were invited to continue in the extension treatment period (Part B).
Non-responder participants, observed within the first 16 weeks, were offered to be treated by open-label sarilumab (Part C).

结局指标
主要结局
Percentage of Participants With at Least 2-step Reduction in Vitreous Haze (VH) or Prednisone Dose <10 mg/Day at Week 16
时间窗: Week 16
At least 2-step reduction in VH per central review from baseline was evaluated on Miami 9-step scale. VH is the obscuration of fundus by vitreous cells and protein exudation. Each of the 9-step scale (from grade 0 \[low opacity\] to 8 \[more opacity\]) images (in increasing order of opacity) are equivalent to approximately 0.3 log units of degradation in visual acuity based on the Bangerter calibration. Participants with prednisone dose \<10 mg/day (or equivalent oral corticosteroid) were also evaluated.
